Discuss Multi Cardinality Schema 

@Cheyans
Also we still haven't discussed how you want a multi cardinality schema represented, e.g. https://github.com/FAForever/faftools/blob/feat/clan/faf/api/game_stats_schema.py

seeing how dragonfire has also ran into this issue, we should probably discuss a good solution

@IDragonfire Problem
API `Clan/<id>` should provide
1. clan details
2. List of clan members
